WILLIAM HENRY CORY AND EDWARD CORY, OF NOTTING HILL, ENGLAND,

IMPRQVEMENT lN APPARATUS FOR PREPARING ARTIFECIAL FUEL.

Specification forming part of Letters Patent No. 132,751, dated November5, 1872.

To all whom it may concern:

Be it known that we, WILLIAM HENRY CORY and EDWARD CORY, both of NottingHill, in the county of Middlesex, England, have invented AnImproved Method of Preparing Blocks of Fuel and do hereby declare thatthe followin g description, taken in connection with the accompanyingsheet of drawing hereinafter referred to, forms a full and exactspecification of the same, wherein we have set forth the nature andprinciples of our said improvement, by which our invention may bedistinguished from others of a similar class, together with such partsas we claim and desire to secure by Letters Patent, that is to say- Thisinvention relates to a method of compounding and agglomerating smallcoal, coaldust, or other carbonaceous matter into blocks of fuel bymixing the matter to be agglomerated with certain ingredients whichcause it to cohere and subjecting the mixture to compression in suitablemolds, which are arranged and worked in connection with mechanism fortheir supply and discharge. For this purpose the matter to beagglomerated is mixed with plastic cement, such as Portland, Roman, orPozzola-na cement, or with fire-clay, or other strong plastic clay, anda solution of silicate of soda or silicate of potash. The proportions ofthe ingredients may be varied, but we [ind that from two to four partsby weight of silicate of soda or of potash in solution of a specificgravity about 1.3 with four to five parts of the cementitiousingredients, are sufficient for one hundred parts by weight of thecarbonaceous matter. The materials having been mixed in a pug-mill orother mixing-machine of known construction, are fed into the hopper ofthe machine for compressing and molding, which we will nowdescribe,referring to the accompaning drawing.

Figure 1 represents partly a vertical section and partly a sideelevation of the machine; Fig. 2 represents a plan of the same and Figs.3, 4, 5, 6, and 7 various parts of the machine, which will be referredto more particularly in the course of the description.

The machine consists of a base, I, and a cover, G, connected firmlytogether by a ribbed framing, H. In the center of the base is astandard, F, from which projects a bolt, E, forming an axis for acircular revolving-table,

A, which is held down by the nut in the axis E. The circular table A hasattached to it bevel-gearing O, and a shaft, P, mounted in a bearing, Q,has a bevel-pinionwhich gears into the teeth 0. This shaft, P, beingcaused to revolve by any suitable power, gives rotation to the table Ain the direction of the arrow. The revolving table A has in it severalcavities, B, with rounded corners, which, with their covers and bottoms,presently to be described, constitute molds for the fuel-blocks. One ofthe covers of these molds is shown in longitudinal section in Fig. 5, intransverse section in Fig. 6, and in plan in Fig. 7. It consists of twoparts, L and L fitted to slide in the table to or from the centerthereof. On each of those parts is mounted a roller, L and L whichprojects into a cam-shaped groove formed in the cover G, this cam-shapedgroove being so formed that during one part of the revolution of thetable A the two slides L L are kept apart, as shown in Fig. 7, so as toopen the top of the mold to which they be-' long, and during anotherpart of the revolution they are closed together so as to form a coverfor the mold. It will be observed that these covers are recessed on theunder side, the sides andends oftherecesses beingrounded, so that whenthey cover the mold the block within it has its upper edges rounded off.The bottom of each mold isa plunger, 0, having a projecting edge withrounded angles; at its lower end a roller. This roller runs upon aninclined or helical tram-way, D, of which a plan is shown in Fig. 3, anda side View in Fig. 4. The plungers O with their rollers being carriedround by the rotation of the table A, the rollers in traveling along thetram-wayD during one part of the revolution raise the plungers G upwardand during another part of the revolution allow them to descend. Withinthe projecting edge of the plunger 0 is a falsebottom or inner plunger,M, which rests on a rod, N, worked by alever, so that when the plungersO are at the upper extreme of their stroke, as determined by theposition of their rollers on the incline D, the inner plungers M liftthe block formed in the mold above the level of the upper face of thetable A. It will be seen in Fig. 2 that the 4 cover G is of such a formas to leave part of the table A exposed, and that at one side of rear 5rthis exposed part it takes the form of a guide, J. It also supports thehopper K, (shown 1n sectional plan in Fig. 2,) into which the mixture to'be agglomerated is fed. By the rotation of the table A the molds B arebrought successively under the mouth of the hopper K, the covers L Lbeing then withdrawn so of the molds are compressed when the molds reachthe uncovered part of their revolution, their covers L L are withdrawn,and their bottom plungers, still rising, lift the molded blocks out ofthe molds, so that by the continued rotation of the table they arecarried along the guide J. From this part of the machine the blocks maybe removed by hand, but it is more convenient to remove them byapparatus, which we will now describe. The guide J leads to a straightchute, R, leading to an endless band, T, which may be carried along thestackin gground whereon the blocks are stacked to harden and season. Theblocks are transferred from J to T by means of wipers S, fixed on anendless traveling-band above the machine. The traveling-bands S and Fare driven by the gearing and shaft U. The quantity of material fed intoeach mold determines the amount of compression to which it is subjected.This quantity can be adjusted by making the lowest part of the inclineat V a movable plate, which can be raised or lowered byadjusting-screws. This plate being raised, the molds, when presented tothe hopper, have less depth, and consequently receive a smaller supplyof the mixture. Also, that part of the incline D which gives the finalpressure by raising the bottom plungers of the molds just before theyare uncovered, may be a plate, W, supported on powerful springs, whichyield when the pressure exceeds such an amount as may be desired.

Having thus described the nature of our .invention, and the best meanswith which we are acquainted of carryin git into practice, weclaim--- 1. The cover of the mold, consisting of two parts, L and L oneach of which is mounted therollers L L, as and for the purposesdescribed.

2. In combination with the rollers L L mounted on the cover of the mold,the cover Gr provided with a cam-shaped groove, as and for the purposesdescribed.

3; The inner plunger M, resting on a rod, N, and operated by a lever, incombination with the plunger 0, as and for the purposes described.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
